" I also like that you are using a shared cathode resistor and bypass cap for each PP pair, as opposed to the original Magnavox scheme with a single resistor for all four tubes, or separate bypassed resistors for each individual tube. I tried all three cathode biasing schemes, and shared-pairs sounded best to me."
FWIW, I design self biased setups with RC networks shared by a PP pair. The better sound you hear may be coming from compensated differences in the individual tubes of a pair. JMO, economical and good sounding, as a combination, is HARD to argue with.
